防摔耐磨手机壳 (Rugged Phone Case) [00-04s] Material Physics & Elasticity: The scene begins with a close-up on a black liquid silicone phone case against a solid dark background. A robotic test finger presses firmly into the corner of the case. We see the material compress realistically (soft-body physics simulation) and then instantly spring back to its original shape, demonstrating high resilience. The lighting is moody with strong rim lights emphasizing the raised edges around the camera lens (2mm height) designed for protection. [05-10s] High-Impact Drop Test Simulation: The camera pulls back to a wide shot in a concrete industrial testing facility. The phone, encased in the product, is dropped from a height of 1.5 meters. The video switches to "Super Slow Motion" (1000fps style) as the phone hits the rough concrete floor. We see the case absorbing the shockwave (visualized as a faint blue energy pulse dispersing through the silicone) and bouncing safely without the screen touching the ground. The physics of the bounce are heavy and realistic. [11-15s] Extreme Durability Verification: Cut to an extreme macro shot of the case surface. A sharp metal key scrapes violently across the back. The camera follows the key's tip. Surprisingly, no scratch marks are left behind, showing the self-healing coating. The phone is picked up, and the screen is turned on, revealing a flawless display. Text overlay pops up with a metallic sound effect: "Military Grade Protection | Anti-Scratch". Style: High-contrast, rugged, engineering documentary style.
